To all whom it may concern:

Be it known that. 1, hours i Gonn, a citizen ot' the United States, and a resident of lllarshfield, in the county of Coos and State of Oregon, have invented a new and Improved Economizer, of which the following is a. full, clear, and exact description.

Among the principal objects which the present invention has in view are: to pro vide a system for supplying to a furnace 'cupola, air which has been heated by escaphaving connected therewith an economizer constructed in accordance with my invention; Fig. 2 is a vertical section of an upper fragment of the same; Fig. 3 is a cross section taken on the line 33 in Figs. 1 and 2; Fig. 4 is a vertical side view of one of the economizer sections; and 5 is a perspective view of the said section.

Vl hen applied to a cupola in Fig. 1 of the drawings, an

such as shown apy'iaratus con- 7 structed in accordance with the present invention employs a rotary fan i of any desired construction. This fan is driven by a suitable motive power, which is operatively connected with the shaft 8 of the tan by a pulley 9. The fan shown in the drawings is of the centrifugal type, and has a supply duct 10 at. the intake end whereof there is an open hood 10 juxtaposedto the dome of the cupola to receive the warmed air arising therefrom. The delivery duct is divided by a valve 11 into two sections 12 and 13. Intcrnwdiate the valve 11 and fan 7 is a branch duct l l,communicating with a lower section 133 of a supply duct 20 for the cupola. and connected with the bustle 16 thereof. The branch 14; is provided with a suitable valve 17, and the section 15 with a valve 18. From the bustle 1i) extend twyers '19. The lower section 15 of the supply duct is divided from the pipe section 15 by a valve 21. Duct sections 13 and 20 are connected through an economizcr formed from sections 22. l l hen starting the cupola. the valves 11 and 21 are closed, cutting old the sections 13 and 20. In this disposition, the air delivered by the fan 7 is carried by the ducts 14C and 15. bustle 16 and twyers 19, into the cupola. The fumes from the cnpola are, as in ordinary constructions, carried to the dome thereof. When the hood 23 of the cupola 6 is closed, the fumes are conveyed oil by a fiuehaving sections 324 and 24: Interposed between the extremes of said flue sections is the economizer formed by the sections 22, 22. The fumes are compolled to travel through the tortuous passage provided in the economizer, before be ing delivered to the surroui'iding air. lVhen the heat has been produced, the hood 23 is dropped; the valve l? is closed; and the valves 11 and 2i are opened. By the closing of the hood the heated gases are diverted to pass through the said OCOJlOllLlZB-l' and the flue 2-1. liy opening the valves ll and 21 and closing the valve 1?. the air travels through the duct sections 13 and E20 and through the said economizer. The passage through theeconoinizcr is formed to spread the gases in a thin layer. The gases are thus brought into mote complete contact with the walls of the sections 22,

The sections 22 from which the econoinizer is in part constructed are n'ovided each with side walls 26 and bolting' flanges 25 secured thereto. Each frame-like construction thus formed is divided longitudinally and upon the median plane by a parti tion 33. The partition 33 terminaties-against a partition 36 in each of the sections, which. as seen in Fig. 5 of the drawings, extends vertically between the upper and lower walls 26 and from the median plane or the level of the partition 33 outward to the level of the flanges r The partition is cut away to form an opening to register with the partitions 38 which form a passage 34. The partitions 3;), 3G and 3S divide the section into two distinct compartments, each compartment being on opposite sides of the median plane or of the partition 33, and each of the compartments having outlet passages formed by the partitions 36 and 38.

Each section is provided with a partition 33. which partly closes one side ot each section extending between both horizontal walls 26 thereof. and from one vertical wall it; to adjacent the opposite vertical wall to "form a passage therewith to register" with the passage 37 of the adjacent section 22 when two or more sections are united.

Referring to Figs. l and 5 oi? the drawings, it will be understood that the sections 22, when united, are turned to present the passages 34: and 37 of each successive section economizer, or oppositely disposed from the location of the passages 34 and 37, as shown in Fig. 4.01 the drawings, and so with a when the air and gases third and other succeeding sections 22. The sections 22, when thus united, would form in the economizer two continuous channels for gases, one of said channels forming a tortuous path in the horizontal plane, and the other of said channels a tortuous path in the vertical plane; or in other words, the sections of one of said channels communicate through the passages 37, and convey the supply air from the box 35 or duct section 13't-o the duct section 20. The section of the vertical channel communicatesjthrough .the passage 34, and conveys the heated gases from the inner to the outer section 24c of the flue.

, It will be understood from the foregoing that after the hood 23 is lowered to compel the heated gases to travel through the .economizer above described and through the vertical channel and openings 34 thereof, the relatively cool air supply is delivered through the horizontal channel by way of the passage'37 thereof on the wayto the bustle 16 of the cupola. During 'the time are both in the economizer, they are separated by the thin partition 33. To aid the radiation or transfer of heat from said gases to said air,-I-

provide flanges the partitions the channel sections, in line parallel with the travel of the air or gases therein. ,To clean the channel sections thus formed, openings are provided in the vertical sides 39, which are mounted upon 26 at the vertical edge of each of the horizontal channel sections, which openings in service are closed by the doors 30 and 30, said doors, as shown in Fig. 3 of the drawings, being disposed in vertical arrangement on the economizer. WVhen the doors 'are opened or removed, as shown in Fig. 5

of the drawings, it. Will be understood that j a cleaning implement could be moved lengthwise of the channel section, and the flanges 39, which therein extend horizontally, could be thoroughly cleansed.

The walls 26 disposed at the top and bottom of the eeonomizer when the sections are united in service position, have formed 33, and are disposed in each of section of the flue 24:. Any deposit of mineral or liquid held in suspension in the heated gases would collect upon the doors 29, to betherefrom removed and saved.

Having thus described my invention, I claim as new and desire to secure by Letters Patent z- 1. In aneconomi'zer such as described; a plurality of sections adapted to be joined to form two continuous passageways, separated by radiating walls, oneof said passageways having vertical extensions, and the otherof said passageways having horizontal extensions, and arranged to pass the air and gas contained by the one and the other passageway, respectively, completely around and to extend on both sides of the said extensions of each.

2. In an economizer such as described; a

plurality of sections adapted to be joined to' form two continuous passageways separated by radiating walls, one of sald passageways having vertical extensions, and the other of said passageways having horizontal extensions and arranged to pass the air and gas contained by the one and the other passageway, respectively, completely a ound and to extend on both sides of the said extensions of each; and'side openings for said extensions to admit a' cleaning implement.

3. An economizer, comprising a plurality of sections adapted to be joined to form two continuous passageways separated' by radi-- ating walls, one of said passageways having horizontal extensions, and arranged to pass the air and gas contained by the one and the other passageway, respectively, completely around and to extend on both sides of the said extensions of each; and elongated, outwardly-extending radiating flanges placed on said radiating walls in parallel arrangement on each side of the walls and in diametrically opposite arrangement of said flanges on each side of the wall to the flanges on the opposite side thereof In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
